1. Setup
The JOYO JF-34 US Dream Distortion Pedal is designed for guitarists seeking a versatile high-gain distortion. Follow these steps for proper setup:
1.1 Power Supply
The pedal can be powered by a DC 9V power adapter (center negative) or a 9V battery. Ensure the power supply meets the specified voltage and polarity to prevent damage.
- DC 9V Adapter: Connect a standard DC 9V (center negative) power adapter to the "DC 9V" jack on the side of the pedal.
- 9V Battery: To install or replace the battery, open the battery compartment on the underside of the pedal. Connect a 9V battery to the clip and place it inside the compartment.
1.2 Connections
Connect your guitar and amplifier to the pedal using standard 1/4-inch audio cables.
- Input: Connect your guitar to the "IN" jack on the right side of the pedal.
- Output: Connect the "OUT" jack on the left side of the pedal to your amplifier's input.

2. Operating the Pedal
The JF-34 US Dream Distortion Pedal features intuitive controls for shaping your desired tone. Engage the pedal by pressing the footswitch.
2.1 Controls
- Volume: Adjusts the overall output level of the pedal. Use this to balance the volume between the engaged and bypassed states, or to boost your signal.
- Distortion: Controls the amount of gain and distortion applied to your signal. Turn clockwise for more aggressive, high-gain tones.
- Tone: Shapes the tonal characteristics of the distorted sound, ranging from darker, warmer tones (counter-clockwise) to brighter, more cutting tones (clockwise).

2.2 True Bypass
The JF-34 features true bypass wiring, which means that when the pedal is disengaged (bypassed), your guitar's signal passes directly through without any coloration or signal degradation. This ensures your original tone remains unaffected.
2.3 Demonstration Videos

3. Maintenance
Proper maintenance ensures the longevity and optimal performance of your JOYO JF-34 pedal.
3.1 Battery Replacement
If using a 9V battery, replace it when the LED indicator light dims or fails to illuminate when the pedal is engaged. To replace, open the battery compartment on the underside of the pedal, disconnect the old battery, and connect a new 9V battery.
3.2 Cleaning
Wipe the pedal's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish.
3.3 General Care
Store the pedal in a dry environment away from extreme temperatures and direct sunlight. Disconnect power when not in use for extended periods.
4. Troubleshooting
If you encounter issues with your JF-34 pedal, try these common troubleshooting steps:
4.1 No Sound
- Check all cable connections (guitar to IN, OUT to amplifier) to ensure they are secure.
- Verify the power supply is correctly connected and providing the specified DC 9V.
- If using a battery, ensure it is fresh and correctly installed.
- Test with different cables, power supply, or guitar/amp to isolate the problem.
4.2 Unwanted Noise/Hum
- Ensure you are using a regulated DC 9V power supply designed for guitar pedals. Unregulated power supplies can introduce noise.
- Check for ground loops by trying the pedal in a different power outlet or with a battery.
- Ensure all cables are in good condition and properly shielded.
